Abstract
The utility model discloses a wear-resistant tension spring which comprises an integrally formed tension spring body and connecting rings. The connecting rings are arranged at two ends of the tension spring body and are rectangular, and arc-shaped chamfers are arranged at four corners of each connecting ring. The wear-resistant tension spring has the advantages that the connecting rings at the two ends of the tension spring body are rectangular, and four right angles of a square part cannot be abutted onto the inner walls of the connecting rings and continuous rub with the inner walls of the connecting rings when the wear-resistant tension spring is fastened on the square part in a suspension manner, so that the wear-resistant tension spring has a good wear-resistant function.
Description
Technical field
The utility model relates to a kind of wear-resistant extension spring.
Background technique
Traditional termination, extension spring two ends is shaped as circle, when button-head buckles after on square parts, in telescopic process repeatedly, the same position of the button-head inwall of extension spring and the right angle of square parts constantly rub, be very easy to make the frictional position wearing and tearing of extension spring and square parts, while having caused extension spring not reach normal working life, rupture in termination.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wear-resistant extension spring, the connecting ring at this is wear-resistant extension spring two ends with have stronger wear-resistant function after square parts is connected.
For this reason, the wear-resistant extension spring that the utility model provides, comprise the connecting ring at integrated extension spring main body and extension spring main body two ends, the rectangular shape of described connecting ring, four jiaos of band arc anglings of described connecting ring.
In the utility model, the connecting ring at extension spring two ends is rectangular, and while buckling on square parts, four right angles of square parts can not withstand on constantly friction on the connecting ring inwall, thereby make the wear-resistant extension spring that the utility model provides have wear-resistant function preferably.
Description of drawings
The structural representation of the wear-resistant extension spring that Fig. 1 provides for the utility model.
Fig. 2 is the stereogram of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the wear-resistant extension spring that the utility model provides, comprise the connecting ring 2 at integrated extension spring main body 1 and extension spring main body 1 two ends, the rectangular shape of described connecting ring 2, four jiaos of band arc anglings of described connecting ring.In the present embodiment, the two bursts of one of elastic metallic yarn that form extension spring are bent to form extension spring, can make the elasticity of extension spring and intensity better.Extension spring latter end 3 is towards extension spring main body 1 and press close to extension spring main body 1 side, can make extension spring catch on more securely part.
Claims (2)
1. wear-resistant extension spring, comprise and it is characterized in that the connecting ring at integrated extension spring main body and extension spring main body two ends: the rectangular shape of described connecting ring, four jiaos of band arc anglings of described connecting ring.
2. wear-resistant extension spring according to claim 1 is characterized in that: two bursts of one of the elastic metallic yarn of described formation extension spring are bent to form extension spring, and the extension spring latter end is towards the extension spring main body and press close to extension spring main body side.
